'purpose of cooling the water 'which circulates in the cyliiiders of theengines 'and is an improvement on 'Patents #1,019,122, :fi-'1,026,895and v:,1,026,896, granted to me March 5, 1912, and May .21, 1912,respec- 'tively.

The 'primary object o'f 'the invention ,is to provide a cast radiatorcasing which is formed in separate sections in order to obtain lightnessof construction and to provide ease of assembling, 'the casingcontaining upper and 'lower chambers which communicate with tubes of aconstruction set forthcin the above mentioned patents.

Another object of the invention is to provide novel :means of formingthe upper and lower water chambers witliin the radiator casing, whichare in communication with water headers carried by the independent tubeksections andare arranged in interlockingengagement therewith by a novelform of joint and washer, so that an' absolutely tight joint .isobtained between-the chambers and the headers.

The invention further resides infthe novel manner of securingand.positioningthe independent tube sections within the casing, so as topermitof 'the removal of one or 'inore sections from the rear ofthecasing without disassembling the radiator, means being provided forclosing the openings in the water tight chambers in order to permit ofthe further use of the radiator after certain of said sections have beenremoved.

The invention therefore consists of the following 'novel combination'and arrangement of parts, which will beghereinafter more 'fullydescribed,illustratedinifthe accompanying drawings andpointed out in theclaim 'hereto appended.

In 'the usual construction of radiators, the radi'ator prop'er'isordinarily Imade o'f a single casting, which containsthe upper andVlower water'head'e'rs connected together by v .the water circulatingtubes. In 'this form of radiator, 'it 'is 'necessary-to 'make 'thecasting of considerable jthi'ckness 'in 'order ito secure strength andto jprevent-'damage'to the ``casting when 'the Icen'tra'l core 'which4forms the space occupied by vt'lie 'water' circulating tubes isremoved. 'In order'to'p'rese'nt 'a 'neat v*and lattractive appearanceit'is ;necessary ito ,use in connection with this casting a cover orlcasing,'ith'ereby adding to 'the 'cost ofjfinanufa`cture 'andincreasing the amount fio'f'material necessary 'to constructIthefradiator.

. 'l'ii' order to 'overconiethese and 'otheni'disadvantages, thevpresent invention contemj plates -the provision of a casing 'cast in'separate sections, sfo 'that'th'euse' of Lthe above vmentioned centralc'ore ;is dispen's'e'd with and the 'casngimay be'ma'de of a lightercasting.` As shown in 'the 'accompany-ing' drawings, the 'radiatjor'includes Ian upper casting 10 'and `a 'lower casting l'l,'wh`1'ch ar`e'hollow and lprovide upper and' 'lower 'water chambers, 'the formerbeing equipped ;withv a 'waiter 'inlet 12 'and'th'e latterf'wi'thr'anout- "let 13, 'both vof'which 'are-connected to'the- `-w'a'te'rcirculating system of the 'motor in "the usual manner. The 'sections 1'0and' 101 are connectedl ;together 'by a side section 14, 'the 'upperends 'of which 'are "secured 'to inset iio `this purpose these water toemploy an additional cover for the radiator. In order to insure strengthin addition to lightness of construction, the upper section 10 is formedVwith strengthening ribs 19, while the 'side sections 15 are providedwith strengthening ribs 20.'

The water circulating tubes which are similar'in construction to thoseshown in the previously mentioned patents are formed of a single pieceof sheet metal, bent in cross- `Sectional shape shown in Figure 5 andsecured together by a seam 21. The tubes which are indicated at 22 arearranged in independent sections, these sections being vcomposed of aplurality of tubes drawn together at each end by headers 23 and 24, theformer being adapted to communicate witl'the upper water chamber 10A andthe latter with the lower water chamber ll. For chambers are formed withinset portions 25 for the purpose of receiving theseheaders, thechambersbeingalso formed with a plurality of spaced openings 26, one of which isadapted to communicate with each of the headers 23 and 24 throughopenings 2? provided in these headers.

' It is a purpose of the invention to provide an interlocking watertight joint between the independent tube sections and' the upper andlower headers, without the use of solder and this is accomplished byforming the openings 26 with' concentrically arranged seats 28, withinwhich the fianges 29 formed around the openings 27 are adapted to enter,the said fiangesbeing shouldered as shown Between these flangesin theseat 28 is a washer 31, of L-shape in cross-section, so that whenthe'independent ltube sections are positioned within the casing,a doubleinterlocking joint will be formed by means of this washer atthepointsindicated at 32 and 33,

this Vmethod Vof connection serving to center the sections within thecasing, leaving the other portions of the headers 23 ;free of contact,asshown in ,Figure 4 of the'drawings.

Boththe upper, and lowerheaders, which fare included in theseindependenttube sections, are form'edof stamped metal and are stampedyinto an open box-like 'formation having inclined sides to facilitate,the yinsertion andV removal of the sections. The headers are closed bymeans of a separately stamped plate 34, which, as shown in Figure `2,:isof hollow rectangular formation and is arovided with inwardl extending sacin This bolt is adapted Jbling the radiator. described, the sidesections 14 are secured to 'tion at the bottom of these Iceive the tubes22, the transverse side fianges 37 which are formed on these tubesabutting one another. The extreme upper and lower portions 37- are ofjust sufiicient length to overlap-theinwardly extendingvends of thefingers 35 and form a closure for the spaces between 'these fingers. enttube sections are assembled within the headers, the same are dipped inthe usual manner, so that an absolutely water tight joint i s obtainedbetween all of the parts of the sections. i i

By constructing the water tubes in indepenclent sections, should theybecome damaged or leak and in order to provide for the use of theradiator after oneV or inore of these sections have been removed, 'thereis provided a closure for any of the openings 26, which may be readilysecured within these openings to prevent leakage'for escape of Waterfrom either of the water chambers. This closure comprises 'a bolt 38,which is -forned with a T-head 39, which is adapted to engage thesurrounding edges of the opening 26 as shown in Figure 7 ofthe drawings.to receive a gasket 40, which is ofa size to litwithin the seat 28 andis held therein by means of the disk 41, and is secured at 42. iOne ofthe projecting portions of the T-head 39 of the bolt is slightly shorterthan the other section to aid inpositioning the bolt within the opening;

The modification shown in Figures 9 and y10 of the' drawings includesupper and lower water chambers l43 and 44, respectively,

'which are adapted to communicate' with headers 45, and 46 carried bythe' independent tube sections, thejdiference 'of construction beingthat instead Aof these headers having communication with the bottomofthe upper chamberV and the top of the lower After the independi ioochamber, in the present form,'theheaders communicate with each of thesechambers at "the rear thereof as shown at :47 thejoint; at this point,of communication being similar to the onepreviously described in thevfirst mentioned form' v This providesfor' the difference of assem- Inthe construction first the upper casting lOthrough the medium of thescrews 16 dependenttube sections then beingj position and thelowersectionll placed in positube' sections. The casing is thensecured'together by means of the bolts 48, which draw the-upper andlower sectionsyof the casing together andpofsition the headers23 and 24for communication with their respective water chambers.

In assembling the radiator shown inl F igures 9 and 10, the top, bottomand side secpreviously mentioned, the in'- a tions ofthe radiator areassembled and the independent tube sections secured within the openingformed by these sections through the medium of securing bolts 49, whichare engaged within openings provided in the rear walls of the upper andlower chambers 43 and 44. The headers el and 46 are substantiallyL-shaped as shown in Figure 10, the vertical leg of the L beingpositioned behind the water chambers and bolts 49 passing between theadjacent headers as shown in Figure 9. These bolts receive spanners 50,which are adapted to break the space between the adjacent headers andengage over the side edges of the same and are held in position by meansof nuts 51. o

It will be seen that any one of the independent tube sections may beremoved by loosening the bolts and turning the spanners 51, the openingsin the chambers being closed by a previously described means.

It is believed that from the foregoing description, when taken inconnection with the accompanying drawings, that the construction,operation and advantages of the invention will be apparent. The right isreserved removable lower water chamber and side secy tions connectingsaid chambers, removable tube sections connecting the upper and lowervwater chambers including a plurality of water circulating tubes, upperand lower headers in each section which have openings which registerwith openings in the respective lower and upper walls of the upper andlower water chambers, a seat having inclined walls surrounding theopenings of the water chambers the water headers of the tube sectionshaving inclined walls, to facilitate the positioning of the sections.

In testimony whereof I afiix my signature.
